The present invention relates to apparatus and machinery or'working glassv and particularly for joining together hollow pieces OfglSS.. i i i 6 VVarious objects and advantages of the invention will be obvious from the following particular description of one formV of? apparatusembody-ing the invention or from an inspection of the accompanying drawings; I and the invention also consists in certain new and useful features of' construction and comparts hereinafter s et forth-'and L Fig. 3 is a sectional view of the chuck.

In the drawings the table -1 carries the upright support 3. from the upper endlofwhich extends'forwardly the pair of armsft, 6 which carry the vertical bearing members comprisingthe horizontal plates 8 and 10 one above the other and withthe pair of aligned4 vertiT cal circular bearing openings 12 'and 14 therethrough.l A vertical hollow shaft 18 eX- tends through said openings 12; and 14 .and is slidable longitudinally therein. A collar` 20 fixed'tozthe upper end of said shaft. 18 limits the downward movement-.thereof in said bearing members 8v and ,10.

Near the lower Vend of' saidhollow-s'haft 18 'and below' said bea-ring member 10. 'is mounted the annular flange 274 having the annular channel 26 formed `inthe lower :face thereof. A lateral opening 2,8 connects -annular channel 26 to a tiexible hose 30 `and thereby to a source of heating gasnot shown. The pins 32, `32 fixed. to the upper side of; Said annular. ange 24 and extending upwardy through holes 34, 34 in Ysaid member' l0 serve Y toV keep said annular flange 24 `from rotational 45 movement thereof along the axis of said hel` low shaft 18. Asecondannularxange 35 in the formvofa grooved pulleyY is rotatably mountedabout said hollow 'Shaftl 1,8 .below said annularange 24,11I third. annular Hangs movement while permitting longitudinalV 36 .fixed-to the'lower. end of said hollow shaft 18 serving'to hol'd sai-d pulley flange 35'in position. Sai-d pulley flange. 35 carries a pair 'of downwardly extending pipes37', 37whifch terminate 'in' sets of inwardly projecting gas jets 38, 38. Said' pipes 37register through openings in' said. pulley 351with said annular channel 26 and'thereby' withl said supply hose in any rotational position of said jets-38, 38 with respect to said ange '24 which is fixed yagainst f rotational movement. weightV of said flange 24 cau-sing it to resten said-flange v serves together with oil used for lubrication between these anges to seal said channel 26 against leakage of gas therefrom between these fianges; Another hollow shaft 40 which Visslidable longitudinally within'said hollow shaft 18 carries and forms with other parts `a clamping device and actuating means therefor comprising a spindle 44 which'eXtends into shaft 40 with a sliding fitl and carries Vat'its vlower `end a smaller? spindle 46 which extendsthrou'gh an annular cap 48 fiXedto the lower end oshaft 40.- The opening through hollow shaft 4G isy in the .from illustrated uniform throughout so that a. space is left. between the interior wall thereof` and'fspindle 46 in" which space is mounted about spindle .46 the. Vcompression spring 50 whichAA presses against .the bottom end of spindle 44. and against. the ,inner face'l of cap-48 andten'ds to move said spindles 44 land 46 upwardly. Fixedto said cap 48 and extendinggradially therefrom at an angle to thefaxis of shat40 area plurality, preferably four, of; rods352. 52;;which ,are connected 'at their `outer ends by the vhorseshoe shaped The plate 54 whchfzpresents the opening ,atfthe f `iront. On 'eachfof rods 52,V A52 is slidably mounted a' clampingrnember 56 which carries .aboss M58Lhavingf an opening therethrough through which the respective rod. 52 extends. Asshown each of the members 56 is afiat plate having verticalinner edges'O, 60 facngtoward a common center andmovable toward and i'rom each other and adapted to such as glass rods or tubing.

C1wiping and @clamping movement is i clampstraigfht sided obiects of various sizes imo, Y

` and which slidably engages the upper and lower surfaces of horizontal slots 64, 64 formedin respective members 56, 56 near the upper ends thereof.A The inclination of said rods 52, 52 from the vertical causes niembers V56, 56 to move toward and from each othei'fhorizontally as said member agira-inst either up'perork lower v`surfacesfof v said slots 64 respectively. Y l

Said member 62 is actuated members 56, 56 in clamping'moveinent by said spring 50 which tends to ,move spindles 44 and 46 and said 1`nemb`er`62upwardly.v

Unclamping movement is yimparted-*tofthe members 56, 56 by means-of the lever 65 which through handle 66 vcan-'be made to bear on the upper side of a stud 67 :fixed to said spindle 44 and extending through a longitudinal slot 68 in said shaft 40 and a slot 69inshaft 18.- This unclamping pressure is applied against the pressure ofspring 50.

Rotation is imparted to flange` and jets 38, 38 by means :of m-otor 86 andthe belt 88 which ridesfinthe annular groove '90 formed around flange 35. The sheave 92 tightened by spring 93 serves to hold said-belt 88at a'suitabletension when the jets38, 38 land flanges 24and V35 are raised'and lowered.

RaisingV and lowering of the jets 38, 38 is achieved'by'means of handle 96 andarm 98 which connect with said shaft18. -Said shaft :and clamping elements carried thereby aremovable1 `vertically by means of a. stu-d 102 fixed in said shaft'40' and extending through r-the sloti104l on the sideofsaid hollow shaftf`18 nearthe stud67, shaft 40 actuation being imparted through the handle 106 Ywhich carries a fork'member *108 which i engages said` stud102 eitherside thereoff' Control of the rotation 'of sai'd jets 38,' 378 by said motor V86is maintained through v`the clutchv memberrllOv mounted to the shaft of said motor 86- and a cooperating clutch member 112`mounted ona shaft 114. Said shaft 114 carries arworm 116 movable longitudinally thereon for a .short distanceibut fixed against rotational movement with` respect thereto and 'said shaftf'114 "isitself slidable Y longitudinally in its lb'earing'sfl18, 118 toengage and disengage said-clutch'- member 112 withand -from the said clutch memberllO, actuation vthereof -f-or this-purpose being securedv byA the chain 120 connecting to aE foot pedal notshowm'the'crank V122 and the anges 124, 126 iixedtosaidjs'haft 114' and positioned 'on either iside ofthe upper y'end of saidi'bell crank 122.7-9Said worm 116 meshes v with aY pinion 4128 Imou'ntedto aV rota-tgV y able shaft 13G-which also 'c arriesa' driving to lftabl'e" 11Y the hollow "casting'f140 which for moving standard 142 in which is slidably mounted i the support standard 143" which at its upper end carries the plate member 144 hayingsaan inclined upper surfaceV 146.

Said hollow casting 140 carries said standi l ard 142 by means of'aball 186 Vattached to the -lowe end? of Y standard 142 and' 'mounted Within'said hollowcasting-140, saidst'andard 142 extending through an opening 1881i`n said casting 140, which opening' is a little -larger than the diameter of the standard 1421but smaller than the-'diameterof saidball `186.

' Fixed'fto saidrtable 1l andv said hollow lcasting 140V is anotherhollow casting 190 which carriesthereinlthe compressionspring 1 92which bearsl at Vone `end against the lbottom'ofy said casting 190 and at'fits upper end against the bally 186 and 4serves to'A frictionally hold said standard 142 by means'of'said ball 186 in any positionto whichit maybe moved as permit-` ted` by'tlie'limi'ts of sadopening 188.

` In the use ond operation of the embodiment of the invention illustrated for 1'joining' two pieces of hollow glassware the operation can be as follows: A hollow glass bulb 158 having a stem 16() formed thereon near one end and a tubular blow-out 196 formed near its other end is mounted -on said plate 144 with said tube 160 mounted between the spring clamping fingers 162, 162 and against said piece of felt 164 with said opening 196 directed upwardly. Another hollow glass member 200 having one end closed and an Velectrode wire 202 sealed in at the closed end is mounted between said clamping jaws 56, 56 with the open en d down. Said opening 196 is aligned with respect to the lower end of said tube 20() by moving the supporting standard 142 about on its ball and socket support, Said bulb 158 being raised to a position in which said opening 196 is close to said tube 200. by means of said cam 17 6, which position is between the flames of said jets 38, 38, and further alignment is made when necessary by further lateral movement of said standard 142. By means of said handles 96 and 106 respectively said tube 200 and the fires on said jets 38, 38 are brought into operative position with respect to Vsaid opening 196, the fires being rotated meanwhile.

When the glass at these parts has become suficiently fused the tube 200 is dropped downwardly against the glass at saidl opening 196 `and the fused glassesare welded together,

pressure within the hollow parts being regulated to shape the molten glass to the desired form by the application of a linger of the operator to said by-pass opening 156. At this time further alignment when necessary can be made of said tube 200 and said opening 196 by lateral movement of standard 142 to properly position said tube 200 with respect to said bulb 158 and tube 160. The glass parts described herein in the example of operation of the embodiment-of the invention illustrated comprise the mercury cathode bulb ofa mercury vapor arc lamp with an electrode seal-in spliced thereto and a tube thereon for sealing to the cylindrical tube which encloses the arc space of such a lamp. Whenthe seal-in of said tube 200 to bulb 158 is completed said clamp members 56, 56 are opened through said handle 66 and standard 143 is lowered by. returning said cam 176 to its original position. The tube 160 is then released from the clamp members 162, 162 and new parts inserted in the machine for the continuation of the splicing operations.
